Adds `ObjectMeta.GenerateName`, an optional string field that defines name generation behavior if a Name is not provided. Adds `pkg/api/rest`, which defines the default Kubernetes API pattern for creation (and will cover update as well). Will allow registries and REST objects to be merged by moving logic on api out of those places. Add `pkg/api/rest/resttest`, which will be the test suite that verifies a RESTStorage object follows the Kubernetes API conventions and begin reducing our duplicated tests.
